1x4gb and 2x8gb RAM. Best configuration? Ram disk?

post #1 of 3
Thread Starter 
Hey all.

So I had 8 gb of RAM but a stick died frown.gif

My brother is going to buy me some RAM for x-mas. He said he'd spend about 80 bucks so that's 2x8gb right there. Now, correct me if i'm wrong but the general consensus still seems to be that anything above 8 is overkill? Still so? I was thinking of having 16gb and using my old 4gb for a RAM disk. Or even an 8gb and a 4gb stick for my memory and 8gb for a RAM disk. However, would having a 4gb and an 8gb stick still allow me to take advantage of the dual channel slots? Would the different sizes cause any wonkyness there, or no?

Just trying to figure out the best set up here. Let me know what you guys think.


Finally i have one last question. I'm a little confused on something. Allow me to explain. My manual for my motherboard states the following

"You may install varying memory sizes in channel A and channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher sized channel is then mapped for single-channel operation."

I had to read it like 5 times but I think I understand now actually. A1 and B1 are one pair of dual channel sockets and A2 and B2 are the 2nd pair. I believe what the manual is saying is that if for example I had a 4gb stick in A1 and an 8gb stick in B1 it would map it as 2 4gb sticks in dual-channel and the additional 4gb leftover from the 8gb stick it would map as it's own channel even though it's one stick? Basically half that stick is mapped as the dual channel and the other half is mapped as it's own? Weird.

Okay, sorry this is long. Replies appreciated!

I am wondering about something similar myself. I have 4x4GB DDR3-2133 in my Rampage 4 Extreme (quad channel), but I have 2x2GB Samsung sticks sitting around doing nothing. I have been contemplating sticking them in and overclocking them to similar speeds, but dedicating them to use in a RAMdisk.

I have been hesitant, though, as they are not only different size but will likely end up being a different speed as well.
Would doing this be at all beneficial, or would it simply have no benefits or even be a step backwards?

The big thing is to have 4GB or more RAM available for Windows. I really don't recommend using a RAMdisk bigger than 4GB unless you have a crazy amount of programs or you have enough RAM (which it doesn't sound like you have) to run steam and a game or two from it. With a 4GB ramdisk I have all my programs and /tmp and /TEMP on it and only kept MS programs (I'm worried about how they update) off it. Windows has suddenly become bearable because of this. This also still left me with 8GB for windows. To me this almost has left the need for an SSD as an afterthought if it wasn't for my gaming.
